The input bias current of J-FET operational amplifier is the PN junction leakage current of the gate, channel and gate, and substrate. Operational Amplifiers and Linear Integrated Circuits_Coughlin. Similar equations have been developed in other books, but the presentation here empha-sizes material required for speedy op amp design. Oscillator operation is based on positive feedback whereby portion β of the output signal V out is feedback without phase φ change. Therefore, the temperature dependence is increased exponentially by the temperature just like as the general PN junction. A summing amplifier is an inverted OP-Amp that can accept two or more inputs. Many oscillator circuits can be designed using operational amplifier circuit.
